The hill of Montesiepi is where ended the parabola of King Arthur’s sword, once Excalibur (out of the stone), now Incalibur (into the stone). But it took all of the might of Michael the Archangel to put it back there and overcome Arthur’s sword carrier Galgano (Gawain). Hehad been poisoned by such a high duty; like all, high things the sword possessed a dark side, which made it hard to relinquish or be relinquished.
